Exercice 69 :
a) 2 (3x - 1) - 5 = x + 1
2 * 3x + 2 * (- 1) - 5 = x + 1
6x - 2 - 5 = x + 1
6x - 7 = x + 1
6x - x = 1 + 7
5x = 8
x = 8/5
b) - 3x + 4 = 2 (x + 2/5)
- 3x + 4 = 2 * x + 2 * 2/5
- 3x + 4 = 2x + 4/5
- 3x - 2x = 4/5 - 4
- 5x = - 16/5
x = - 16/5 : (- 5)
x = 16/25
c) 3 (x - 2) - 1 = - 2 (x + 4)
3 * x + 3 * (- 2) - 1 = - 2 * x - 2 * 4
3x - 6 - 1 = - 2x - 8
3x + 2x = - 8 + 6 + 1
5x = - 1
x = - 1/5
d) 2 (4 - 3x) = - (x + 5)
2 * 4 + 2 * (- 3x) = - x - 5
8 - 6x = - x - 5
- 6x + x = - 5 - 8
- 5x = - 13
x = - 13 / (- 5)
x = 13/5
